Is Acne Contagious?

No. Acne is not contagious. You cannot catch it from touching someone, kissing, sharing a towel or using the same pillow. Acne develops inside your own hair follicles because of oil production, blocked pores, inflammation and hormonal sensitivity. The bacteria involved live on almost everyone's skin, so you are not passing anything new to anyone.

It is a question a lot of people are too embarrassed to ask, and the myth does real harm. People with acne are sometimes treated as if they are unclean or infectious. They are neither. Here is what is actually going on.

Why acne is not contagious

Acne starts when a hair follicle becomes blocked with oil and skin cells. Inside that blocked pore, bacteria that normally live on the skin can multiply and trigger inflammation. That is why spots become red, swollen or filled with pus.

The key point is that these bacteria are part of normal skin for nearly everyone, with or without acne. What makes acne happen is the environment inside your own follicles: how much oil your glands make, how your skin cells shed, how your skin reacts to normal hormones and how strongly it becomes inflamed. Those things are about your skin and your genes, not about contact with other people.

The UK Primary Care Dermatology Society's patient leaflet puts it simply: acne is not contagious and cannot be passed on to other people.

Can I get acne from a partner, a pillowcase or a phone?

A partner. No. Kissing or being close to someone with acne will not give you acne.
Pillowcases and towels. Sharing them will not spread acne. Pressure, friction and heavy hair or skin products on fabric can aggravate spots that are already there, but that is not infection.
Phones, helmets and face masks. Repeated pressure, heat and sweat in one area can worsen acne where they touch the skin. This is called acne mechanica, and it is about friction, not germs from someone else.

If it is not contagious, is it a hygiene problem?

No, and this is the other myth worth clearing up. Acne is not caused by dirty skin, and washing more does not cure it. Scrubbing and over-cleansing usually irritate the skin and can make acne look worse. A gentle cleanser twice a day is plenty.

Acne is a medical condition. It is common, it is nobody's fault and it responds to the right treatment.

Skin conditions that can look like acne and are contagious

Some spots that look like acne at first glance are a different condition, and a few of these can spread. That is one reason a proper diagnosis matters.

Impetigo. A skin infection that starts as red sores or blisters, which burst and leave crusty, golden-brown patches. The HSE describes it as very contagious.
Cold sores. Clusters of small, painful blisters, usually on or near the lips, often with tingling first. They are caused by a virus and can be passed on through close contact.

If your "spots" are crusting, weeping, blistering, spreading quickly or appeared suddenly along with feeling unwell, have them checked rather than treating them as acne.

Why the myth matters

Being treated as if your skin is something to avoid is hurtful. Acne already affects confidence, mood and how people go about their day, and that impact is well documented. If you have been made to feel unclean because of your skin, that says more about the myth than about you.

If you are a parent, it is worth saying this out loud to a teenager with acne. Knowing it is not their fault, and not something they are spreading, can take some of the shame out of it.

When should I see a doctor?

You are not sure your spots are acne, especially if they crust, blister, itch a lot or spread quickly
You have deep, painful lumps or your acne is leaving marks or scars
Pharmacy products have not helped after two to three months of regular use
Acne is affecting your confidence, relationships or mood

If acne is affecting your mental health, please tell your doctor. It is a valid reason to seek help, and I ask about it at every review.

Frequently asked questions

Can acne spread from one part of my face to another?

Not in the way an infection spreads. New spots appear in new places because more follicles are becoming blocked and inflamed. Picking and squeezing can make individual spots worse and increase the risk of marks, but they do not spread acne across your face.

Is back acne contagious?

No. Acne on the back, chest and shoulders works the same way as facial acne and cannot be passed on.

Is fungal acne contagious?

"Fungal acne" is a different condition from acne, caused by yeast that normally lives on the skin overgrowing in the follicles. It is usually linked to heat, sweat and other factors in your own skin rather than catching it from someone. If you think you have it, get it assessed, because ordinary acne treatments do not treat it.

Can I share makeup if I have acne?

Sharing makeup will not give someone acne. It is still sensible not to share makeup or brushes, because they can carry infections such as cold sores or conjunctivitis.

Is cystic acne contagious?

No. Cystic and nodular acne are severe forms of acne, not an infection you can pass on. They do carry a higher risk of scarring, so they are worth treating early.
